How many chromosome are in the original cell compared to those in the new cells formed by cell division?
They have exactly the same number of chromosomes. That is what Mitosis does- it creates two genetically identical cells.
The tricky part in understanding Mitosis is that each of the CHROMOSOMES in the new cells will only have one CHROMATID. Prior to the completion of Mitosis, each of the chromosomes in the original cell had two sister chromatids connected at the Centromere- but this is still considered only ONE chromosome.
When a cell is preparing for division, the chromosomes (each with just one chromatid) undergo DNA replication so that each chromosome has two identical sister chromatids. This enables the cell to divide evenly (with each daughter cell getting a full set of chromosomes, each with one chromatid). A human cell that has undergone mitosis is still Diploid (two of each type of chromosome- two of Chromosome 3, two of Chromosome 21, etc), even though each chromosome only has one chromatid. Only cells that have undergone MEIOSIS become haploid (in Meiosis, not only do the chromatids separate, but the matched pairs of chromosomes separated as well, so that each daughter cell only gets ONE of each type of chromosome).

Determine how many chromosomes are in the original cell compared to those in the new cell formed by cell division Explain?
The original cell and the new cell formed by cell division have the same number of chromosomes. In most cases, cell division, whether through mitosis or meiosis, results in daughter cells with an identical set of chromosomes to the parent cell, maintaining the chromosome number of the species.
How do the new cells formed after mitosis and cytokinesis compare in size and chromosome number to each other and the original cell that divide?
The new cells formed after mitosis and cytokinesis are usually similar in size and chromosome number to each other. They are typically identical to the original cell that underwent division, as the purpose of mitosis is to produce genetically identical daughter cells. However, there can be exceptions such as during meiosis when the chromosome number differs between the original cell and the new cells.
Double cell division process that leaves the four newly formed cells with half the chromosomes of the original cell?
Meiosis is the double cell division process that results in four haploid cells, each with half the number of chromosomes as the original diploid cell. Meiosis involves two rounds of division (meiosis I and meiosis II), which reduce the chromosome number from diploid to haploid. This process is important for sexual reproduction in eukaryotic organisms.
One of the two homologous strands of a chromosome?
A homologous strand of a chromosome is a duplicated copy of the original chromosome, formed during DNA replication. It contains the same genetic information as the original chromosome and is held together by a centromere. Homologous chromosomes play a key role in meiosis, where they pair up and exchange genetic material during crossing over.
What is the structure that holds each chromosome to its exact copy?
The structure that holds each chromosome to its exact copy is called a centromere. The centromere is a region of the chromosome that serves as the attachment point for the two sister chromatids, which are the identical copies of the chromosome formed during DNA replication. The centromere plays a crucial role in ensuring the accurate segregation of chromosomes during cell division.
How many chromosome are in the original cell compared to those in the new formed by cell division?
If the cell division follows mitosis, the number of chromosomes in original cell and new cells remain the same. During meiosis the new cells formed have half the number of chromosomes of original cell.
Determine how many chromosomes are in the original cell compared to those in the new cell formed by cell division Explain?
The original cell and the new cell formed by cell division have the same number of chromosomes. In most cases, cell division, whether through mitosis or meiosis, results in daughter cells with an identical set of chromosomes to the parent cell, maintaining the chromosome number of the species.
How many DNAmolecules make up each original chromosome?
A chromosome is formed from a single DNA molecule.
How do the new cells formed after mitosis and cytokinesis compare in size and chromosome number to each other and the original cell that divide?
The new cells formed after mitosis and cytokinesis are usually similar in size and chromosome number to each other. They are typically identical to the original cell that underwent division, as the purpose of mitosis is to produce genetically identical daughter cells. However, there can be exceptions such as during meiosis when the chromosome number differs between the original cell and the new cells.
If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes

How are sister chromatids formed during the process of cell division?
During cell division, sister chromatids are formed when a single chromosome replicates to create two identical copies. These copies are held together at a region called the centromere, resulting in the formation of sister chromatids.
What are two cells formed after mitosis and cell division?
The two new cells formed after mitosis and cell division are called daughter cell. Their nucleus is genetically identical to the nucleus of the original cell .The two new cells formed after mitosis and cell division. There are no differences between the two cells. They have the same number of chromosomes after division.
What is the process when reproductive cells are formed?
Reproductive cells, also known as gametes, are formed through a specialized cell division process called meiosis. During meiosis, a single cell undergoes two rounds of division to produce four daughter cells, each with half the number of chromosomes as the original cell. This reduction in chromosome number is essential for maintaining the correct number of chromosomes when the gametes fuse during fertilization.
Why are new cells formed the same as the original cell during cell division?
because they have the same DNA
How many cells are formed after cell division?
When body cells (somatic) undergo cell division (mitosis) It creates a duplicate cell. So for every cell undergoing cellular division, one new cell plus will be formed and the original will remain.
